Superfamily: RecBCD complex, subunit RecD, N-terminal domain

RecBCD is a multi-functional enzyme complex that processes DNA ends resulting from a double-strand break. RecBCD is a bipolar helicase that splits the duplex into its component strands and digests them until encountering a recombinational hotspot (Chi site). The RecD subunit accounts for the 5'-3' helicase activity of RecBCD. The structure of the RecD subunit resembles SF1 helicase. RecD comprises several domains - N-terminal domain, domains 1A, 1B, 2A (or 3) and 2B (in D. radiodurans RecD2). This superfamily entry represents the N-terminal domain of RecD subunit.
